标签: javascript ajax autocomplete yui widget

数据:

JACKSON, MS 39212|39212
BAINVILLE, MT 59212|59212
CROOKSTON, NE 69212|69212
COLUMBIA, SC 29212|29212
SPOKANE, WA 99212|99212

代码:

    <form method="GET" target="_blank">
        <fieldset><legend>remote example</legend>
        <label for="myRemoteInput">Enter a state:</label>
        <div id="myRemoteAutoComplete">
                <input id="myRemoteInput" name="myRemoteInput" type="text">
                <div id="myRemoteContainer"></div>
        </div>
        </fieldset>
        <input type="submit" />
    </form>
<script type="text/javascript">
YAHOO.example.BasicRemote = function() {
    var oRDS = new YAHOO.util.XHRDataSource("data.php");
    oRDS.responseType = YAHOO.util.XHRDataSource.TYPE_TEXT;
    oRDS.responseSchema = {
        recordDelim: "\n",
        fieldDelim: "|"
    };
    oRDS.maxCacheEntries = 5;
    var oRAC = new YAHOO.widget.AutoComplete("myRemoteInput"
        , "myRemoteContainer"
        , oRDS
        , {minQueryLength: 2,maxResultsDisplayed: 25, forceSelection: true});

    return {
        oRDS: oRDS,
        oRAC: oRAC
    };
}();
</script>

方案: 我想显示带有City,ST zip值的自动完成小部件,但是,表单字段myRemoteInput总是填充所选的City,ST zip值。

问题: 当用户从自动完成下拉列表中选择City,ST zip值时,如何使用zipcode填充表单字段myRemoteInput值?

自定义事件itemSelectEvent可能就是您要查找的内容。我自己从未使用它,但它可能类似于

oRAC.itemSelectEvent.subscribe(onItemSelect);

function onItemSelect(oSelf , elItem , oData) {
    var locationData = oData[0];
    // Now parse location data and put only the ZIP code back into oData[0]
}

How do I change YUI Autocomplete textfield Value population Options?得到了这个并稍微调整了一下。我不知道这是否有效,但它可能会让你开始。

我想你知道API,但以防万一:http://developer.yahoo.com/yui/docs/YAHOO.widget.AutoComplete.html
